Gives a good sense of security

Before buying, I vacillated between an ironing and folding lock, then decided but this because it seemed to me more flexible. Despite the numerous notes I was surprised about the weight of the lock. I have attached the bracket to the water bottle holder (conveniently, the screws for the bike usually already exist). There, the castle sits stably and is very easy to take out of the holder. Attach the bracket to the existing Velcro appeared too risky (risk of theft) me. During the trip, nothing wobbles. However, you can feel the weight when cycling.
The length of the castle is completely sufficient to fasten the rear wheel and frame to not to thick poles, traffic signs, lampposts. I was initially concerned that the length would be too short (of course, the 85cm refers to the scope of the castle!), However, is by the ruler character greater flexibility given. Rotate With some back and forth, you get attached to the wheel safely.
You really have to make sure that the key is rotated accurately and properly inserted before you turn, otherwise the opening may be somewhat hakelig.
In my opinion, Abus would calm can handle more chain links slightly so that the closing would be even more flexible.
